Abstract:
The thesis is an introduction to our attempts to evaluate
the coordination behaviour of a few compounds of our interest.
Semicarbazones and their metal complexes have been an active area of
research during the past years because of the beneficial biological activities
of these substances. Tridentate NNO semicarbazone systems formed from
heterocyclic and aromatic carbonyl compounds and their transition metal
complexes are well-authenticated compounds in this field and their
synthesis and characterization are well desirable. Hence, we decided to
develop a research program aimed at the synthesis and characterization of
novel semicarbazones derived from 2-benzoylpyridine and 2-acetylpyridine
and their transition metal complexes. In addition to various physicochemical
methods of analysis, single crystal X—Ray diffraction studies were
also used for the characterization of the complexes.

Abstract:
In the present work,the chelating behaviour of thiosemicarbazones of a heterocyclic diketone, 2,6-diacetylpyridine is studied,with the aim of investigating the influence coordination exerts on their conformation and /or configuration, in connection with the nature of the metal and of the counter ion.The various possibilities like unsubstitution,ring incorporation at terminal nitrogen and condensation of one of the ketone group alone have been tried for ligand selection.Mainly first row transition metals like manganese,iron,nickel,copper,zinc and cadmium are studied.Metals like cobalt also were studied but could not result in fruitful isolation of the compound due to solubility problems.Different spectroscopic and characterization techniques have been utilized to reveal the nature of the metal and the ligands in coordinated metal complex.
